The wallet is the first real app because receipts travel with the user, QR verification is mobile-native, and WhatsApp sharing is the default trust gesture for many mobile-first regions.
Do not try to ship all 14 platforms as apps. Ship the wallet first because every other workflow eventually deposits a receipt into it.
iOS and Android from one shared codebase; local encrypted storage; receipt import by QR, deep link, JSON file, clipboard, and raw JSON; receipt list/detail; L0-L2 local verification; WhatsApp/email/system share/QR/PDF; Life Proof Archive export; five languages.
No cloud sync, no L3/L4 registry lookup, no signing new receipts on device, no ID scanning, no biometrics, no chat, no push notifications, no subscriptions, no Apple/Google Wallet passes in v1.
East Africa is mobile-first, often intermittent-data, and WhatsApp/QR are natural trust gestures. The wallet becomes the daily proof surface.
Use this page as the public build brief for fixed-price quotes. If a contractor cannot answer the screening questions confidently, do not hire them.
Target a focused East African or South Asian contractor/studio range of USD 12,000 to 18,000 for a fixed-scope 8–10 week build. Treat shorter than 6 weeks as suspicious and longer than 14 weeks as inflated unless justified.
The Wallet v1 is the only mobile build target. The platforms become proof lanes, receipt templates, QR/deep links, issuer portal actions, and reviewer workflows.
Proof Yearbook timeline, QR verifier, WhatsApp sharing/verification, AI agent authorization receipt, creator proof packet, and selected archive export.
No 14-app build, no generic AI chatbot, no universal database of human identity, and no claims of legal recognition without counsel and pilot evidence.
Wallet first, issuer portal second, public verifier always, refusal log always, reviewer registry visible, and standards mapping public.
